Underground interchange merge area sight line induction system

Abstract

The invention relates to the technical field of traffic safety, in particular to an underground interchange merge area sight line induction system comprising a side wall sight line induction system, asign induction system and a road surface induction system. The side wall sight line induction system is composed of light reflection rings, curb vertical face signs, waistband lines, induction largearrows, induction small arrows and LED reference strips. The sign induction system is composed of flexible warning columns, a merge warning sign, a give-way sign and tunnel indicators. The road surface induction system is composed of protruding road signs, flow guide lines, a dotted and solid turning arrow, a give-way mark line, fishbone-shaped speed reduction mark lines and a dotted and solid mark line. Due to the adoption of the structure arrangement, by means of the side wall sight line induction system, the sign induction system and the road surface induction system, the visual environmentof drivers is effectively improved, the induction and indication effects of secondary road traffic flow are enhanced, the passage efficiency of merge areas is improved, the vehicle speeds and the vehicle distances of vehicles on primary roads and secondary roads are controlled, and safety of the merge areas is improved.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an underground overpass merging line of sight induction system. Background technique [0002] At present, on the one hand, more and more tunnels, underground interchanges, and interweaving are becoming more and more with the urban construction. Research on the theory of traffic flow system in the urban underground interchange junction area, so the lack of hierarchy, systematicness, and accuracy of the guidance information often leads to driving difficulties for drivers, resulting in congestion and traffic accidents in underground interchanges, and affecting the regional traffic environment . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an underground overpass merging line of sight induction system, which improves the driver's visual environment, enhances the effect of inducing and indicating the traffic f...
